Signed to a $120.6 million contract during the offseason, quarterback Joe Flacco threw two interceptions as he continues to get acclimated to a new group of receivers. He completed 34 of 62 passes for 362 yards and two touchdowns for a 69.4 quarterback rating while being sacked four times.

Tight ends Dallas Clark and Ed Dickson struggled with dropped passes. The Broncos stopped the Ravens' running game, limiting them to 58 yards on 21 carries, a 2.8 average per rush. And the defending Super Bowl champions finished with an average of 4.5 yards per play.

Althuogh the Ravens are adjusting to a lot of change offensively, offensive coordinator Jim Caldwell made no excuses for what happened and referred to his book of quotations in doing so.

"Our standards around here are high," Caldwell said. "We’re not looking for any excuse. You’ve probably heard the old saying, ‘Excuses are tools of incompetence. They’re used by monuments of nothingness. Those who specialize in them are seldom good at anything else.’

"We tend not to want to lean on any. Our standards are high, we focus on getting better, and we expect to be better. We will be better, no question about that.”

The Ravens re-signed wide receiver Tandon Doss this week after losing Pro Bowl kick returner Jacoby Jones for the next four to six weeks with a sprained medial collateral ligament in his right knee.

"Jacoby is a dynamic player, a very talented guy," Caldwell said. "I think we have some guys that can step in and certainly fill in that role. We have some talented guys we think will be able to do that. We just have to anticipate that we’re going to be able to step up and do the things we’re capable of doing in the pass game, do the things we’re capable of doing in the run game and battle a real tough team this week.”

A 2011 fourth-round draft pick from Indiana, Doss was released after catching seven passes last season.

Wide receiver Deonte Thompson remains sidelined with a sprained left foot and rookie Aaron Mellette was placed on injured reserve with the team citing a knee injury.

"We’re working him in to our rotation," Caldwell said of Doss. "He’s capable. There’s no question about that. That’s why we brought him back. He’s a guy that knew our system, knew it well.

"It wouldn’t take long to get him up to speed. Obviously, we’ve put some new things in since his departure. We’re certainly glad to have him back.”
